    • Constructor Detail

      • AbstractListChromosome

        public AbstractListChromosome​(java.util.List<T> representation)
        Constructor.
        Parameters:
        representation - inner representation of the chromosome

      • AbstractListChromosome

        public AbstractListChromosome​(T[] representation)
        Constructor.
        Parameters:
        representation - inner representation of the chromosome

    • Method Detail

      • checkValidity

        protected abstract void checkValidity​(java.util.List<T> chromosomeRepresentation)
                               throws InvalidRepresentationException
        Asserts that representation can represent a valid chromosome.
        Parameters:
        chromosomeRepresentation - representation of the chromosome
        Throws:
        InvalidRepresentationException - iff the representation can not represent a valid chromosome

      • getRepresentation

        protected java.util.List<T> getRepresentation()
        Returns the (immutable) inner representation of the chromosome.
        Returns:
        the representation of the chromosome

      • getLength

        public int getLength()
        Returns the length of the chromosome.
        Returns:
        the length of the chromosome

      • newFixedLengthChromosome

        public abstract AbstractListChromosome<T> newFixedLengthChromosome​(java.util.List<T> chromosomeRepresentation)
        Creates a new instance of the same class as this is, with a given arrayRepresentation. This is needed in crossover and mutation operators, where we need a new instance of the same class, but with different array representation. Usually, this method just calls a constructor of the class.
        Parameters:
        chromosomeRepresentation - the inner array representation of the new chromosome.
        Returns:
        new instance extended from FixedLengthChromosome with the given arrayRepresentation

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class java.lang.Object
